<p>The invention relates to a gripping device with gripping arms (2), which are mounted so as to be displaceable parallel to one another in a supporting piece (7), provided with a suspension device, via two legs (6) each connected to the gripping arms (2) at an angle, and at least one linear drive, preferably a hydraulic piston/cylinder unit (15), moving the gripping arms (2) towards one another and away from one another. The piston/cylinder unit (15) preferably consists of two cylinders (16) arranged essentially parallel to one another and connected to the supporting piece (7). The piston rods (17) of the cylinders (16) are linked to the gripping arms (2), preferably to cross pieces (4) serving as a stop. A gripping device (1) with as uniform a contact pressure of the gripping arms (2) as possible, which is inexpensive to manufacture and is easy to maintain in a simple and inexpensive manner and in particular permits easy and quick exchange of certain components, in particular the drive units, and at the same time fulfils the requirements of the regulations for prevention of accidents, is created by the cylinder or cylinders (16) of the piston/cylinder unit (15) being mounted in their centre area, the mounting (18) being an integral part of the supporting piece (7) and permitting a limited pivoting action of the cylinder or cylinders (16) about their radial axis. … <IMAGE> … </p> |
